NAME

significand, significandf, significandl − get mantissa of floating point number

#include <math.h>

Link with −lm.

The significand() function returns the mantissa of x scaled to the range [1,2). It is equivalent to

scalb(x, (double) −ilogb(x))

This function exists mainly for use in certain standardized tests for IEEE 754 conformance.

This function came from BSD.
